VIDEO CHANNEL CHANGE SYSTEM

摘要

A video channel change system may include one or more processors and a memory. The one or more processors may receive first packets including first video frames associated with a first video channel and second packets including second video frames associated with a second video channel. The one or more processors may decode the first packets and display the first video frames while buffering, in a buffer, the second packets. The one or more processors may determine that a packet of the second packets includes a random access point without decoding the packet, discard the second packets from the buffer that were received prior to the packet, buffer additional second packets received subsequent to the packet, and decode the second packets stored in the buffer and display the second video frames included therein, in response to a request to change from the first video channel to the second video channel.

主权项

1. A method for performing video channel change, the method comprising:
receiving first packets that include first video frames and second packets that include second video frames; decoding the first packets and displaying the first video frames while buffering, in a buffer, the second packets; determining that one of the second packets includes a random access point without decoding the one of the second packets; and discarding the second packets from the buffer that were received prior to the one of the second packets that includes the random access point and buffering, in the buffer, additional second packets received subsequent to the one of the second packets that includes the random access point.
